First, let’s break down each piece of the problem. We have the fraction, 18/31, which is also the dividend, and the whole number, or the divisor, which is 39:
Numerator of the dividend: 18
Denominator of the dividend: 31
Whole number and divisor: 39
So what is 18/31 Divided by 39? Let’s work through the problem, and find the answer in both fraction and decimal forms.
First let’s set up the problem:
Step 1:
Take the whole number, 39, and multiply it by the denominator of the fraction, 31:
31 x 39 = 1209
Step 2:
The result of this multiplication will now become the denominator of the answer. The answer to the problem in fraction form can now be seen:
To display the answer to 18/31 Divided by 39 in decimal form, you can divide the numerator, 1209, by the denominator, 18. The answer can be rounded to the nearest three decimal points, if needed:
So, in decimal form, 18 divided by 31/39 = 67.17
And in its simplest fractional form, 18 divided by 31/39 is 403/6
